Just looked at the revival cycles diagram and it is also wrong. Their alternative main fuse circuit is OK, but if you don't use that then there will be no power to the m-unit unless the bike is running.
Edit: So, I guess assumption is the mother of all... I took a closer look at the revival cycles diagram and it looks like they just labelled it in a confusing way. The label "Starter solenoid" and "main fuse" should probably just be combined and put underneath, the way they labelled it I assumed it was two seperate components just stuck together. Internally it seems that the battery positive is bridged to the fuse (blue circle below, this is missing in your diagram). This means that you can wire it up as you had planned. Sorry for any confusion, my mistake.
